PACKLESS VALVE.

Specification of Letters Patent.

Application filed April 12, 1911.

Serial No. 620,571.

To all'whom it may concern Be it 'known that I, FRANK Sormmn'r, a citizen of the United States of America, residing atlilansfield, in the county of Richland and State of Ohio, have invented cer-- tain new and useful Improvements in Packless Valves, of which the following 'is a specification.

My invention relates to packless radiator valves.

The objects of my invention are; to provide means of rotatably suspending a valve stem; to provide means of forcing a soft packing in close contact with the valve stem to prevent leakage past the stem; to provide means of automatically taking up the wear of the parts and packing; to provide means of setting the valve to open more or less and to prevent the further opening of the valve when the valve is opened a predetermined amount; and to provide means 0 releasing the valve from its seat in case of sticking.

In the drawings, Figure 1 represents a crosssectional' sideelevation of my. valve showing it in closed position. Fig 2 represents a to view of the indicator part of the operating handle, cap, regulator ring and stop. Fig. 3 1s a top view of a connecting member provided with a rectangular aperture and a pointer. Fig. 4.- is a cross sectional side elevation of Fig. 3. Fig. 5.

shows the regulator ring having a boss that contacts with a stop pm. Fig. 6' is a bottom view of Fig. 1 taken on the lines wb, showing projecting portion on the valve stem which stops the rotation of the stem 31nd valve when the valve is fully closed or fully open In the drawings, reference numeral 1 rep resents the body of the valve, 2 the inlet and 3 the outlet thereof. A bonnet 1 is preferably made integral with the body but of course can be threadahly connected thereto if desired. The bonnet is provided with an outwardly extending annular flange 5 and the inner periphery of the bonnet is provided with an annular seat 6.

The valve stem 7 carries a valve 8 at its lower end and is inserted in an aperture 9 formed contiguous with the seat 6. Soft packing 10 made of anyflexible material tapered on its lower portion to fit the seat 6 is provided and surrounds the valve stem 7. A loose ring 11 having a tapered seat 12 formed on its lower surface is fitted to surround the valve stem and lie in contact with the tapered top portion of the soft packing 10. A connecting member 13 is provided with an annular rib 14 and is adapted to rest upon the ring 11. The connecting member 13 has an annular groove 15 formed on its outer periphery. A regulator ring 16 is fitted to the outer periphery of the connecting member '13 having an outwardly extending boss 17 interiorly threaded to engage with the set screw 18 which is adapted to enter the groove 15 tomaintain and aidjust the regulator ring. After adjustment,

the size of the opening of the valve is regu'' lated to be opened uniformly by the stop 19.

It will he observed that when the regu lator ring is adjusted, the. boss 1? will contact with the stop 19 which. prevents its further rotation and maintains the predetermined size of the opening uniformly until further ad] desirable.

it will be noted that the connecting memher is provided with arectangular aper-. ture 20 and a pointer 21. The rectangular aperture fits over the rectangular portion.

ustment of the regulator is 22 of the valve stem 7 so that when more ment is imparted to the valve stem. it also imparts movement to the connecting Incinber, the valve stem and vs ve.

The upper portion of the connecting member 13 is cupped at 23 to fit the reduced end 24 of the body portion 25 of the 0 crating lever 25. The portion 25. of the operatinglever is also cupped at 26 and interiorly threaded to engage with the adjustable cap -27 the annular ange (a) of which is adapted to contact with the shouldered 4 portion (7)) of the valve holder 30 and when the valve sticks and the cap is screwed againstt-he valve holder it forces the valve threadnbly engages the threaded end 29 of the valve stain for adjusting the valve stem to force the valve in close contact with its seat. Normally the cap ,2? is retracted to allow the springs to force the valve to its seat. p

A soil compression spring 31 rests upon the shoulder of the cup portion 26 of the body of the operating lever and exerts a pressure against the under surface of an outwardly extending annular flange of the holder. The pressure of the spring against the flange 33 llOl'lHtlllY forces the valve stem in an upward direction and the valve in close and yielding contact with its seat automatically taking up the wear ol? the valve and its seat and forces thesott paclo ing, as it wears, in contact with the stem to prevent; leakage past the stem. he observed that tl c valve holder is adjustable and can be manually screwed down against the tension of tie coil spring Ell forcing the connecting member 13 to torce the loose ring 11 in contact; Will the soft; packing 10 making it lit snugly around the stern.

The outwardly extending flange 5 of the bonnet has numerals embossed on the surface 34 to indicate the extent of the open ing of the valve 8 and the pointer 21 points to the number desired and the boss of the regulating ringis then to contact with the stop when the size ol the opening desired is tlctcri'nined. In setting, the valve to increase or decrease the size of the open in g ol the valve, the set screw 18 is loosened and the regulator ring moved in the direction desired to regulate the flow of the fluid through the valve 8.

A stop 36 is provided to indicate that "tho valve is completely closed or opened.
